The Midnight Library

As a fiction, it has a very nice concept and an alright execution which isn't too corny. I was immersed with the story and did hope the main character the best. I didn't personally like the themes as much, it felt too repetitive, even though technically it made sense since they're all the same person (climate change - a specific philosopher - family - bad life - disappointment or sadness - repeat)

As a self-help book, which it becomes in the second part, it wasn't for me, the only notable thing is that metaphor with chess doesn't make any sense lol, just a nitpick though.
